To aZZ whom it may concern: of the frame. These makingwires are of Be itknown that we, CHARLES H. CASE, a common construction, but have a novelarresident of Highland Park, and JOHN GRAY, rangement. The making-wire 6passes from a resident of South Manchester, in the county the roller 5to the guide-roll over the lower 55 of Hartford and State ofConnecticut, citizens wire roller 11 on the main part of the frame, ofthe United States, have invented a newand and thence to the guide-rollsb b" to the upuseful Machine for Making Paperor the Like, per wireroller 6 Supporting-rollers l) are of which the following is aspecification. mounted in the frame in position to support Our inventionrelates to the manufacture the horizontal part of the making-wire.

out the disadvantage of either, the machine being capable of forming thestuff into a sheet of any desired thickness from the thinnest to thethickest.

It is to be noted that the stuff is delivered to the hopper, two of theOpposing sides of which are formed of the making-wires that travel fromthe top to the bottom of the hopper and approach each other as they nearthe bottom. The stuff is supplied to the hopper mixed with a largeamount of water and in uted throughout the quantity sufficient tomaintain the level of the-stuff within the hopper at the requiredheight. As the fluid mass descends under the action of the travelingmaking-wires it is gradually compressed more and more as it nears thebottom of the hopper, the water at the same time being forced out to adegree through the making wires composing the walls of the hopper. Theadjustable side parts determine the width of the sheet, and by the timethe sheet passes around the guideroll 0 at the bottom of the hopper themass of fiber is formed into a sheet of quite regularconsistencyandveryhomogeneous. From this point it is carried along, passing betweenthe lower making-roll b and the press-roll g, and thence between thefelt roll f and pressroll h, from which point it is conducted to furtherpress-rolls or dry'ing-cylinders,as may be desired.

An advantage derived from this construction resides in the fact thatforeign material, as quite large strips or pieces of tobaccostalks orthe like, can be regularly distribmass as it is formed into a sheet,thus giving to both sides of the sheet when finished all of theadvantages which may reside in a fabric by reason of the presence ofsuch material therein, the surface of both sides of the sheet being.alike and capable of use.

The term making-wire has been used throughout the specification and inthe claims to designate those parts which act upon the pulp whilecontained in the hopper and for removing it therefrom; but we do notdesire to limit ourselves to a making-wire in the sense that it shall becomposed of a metal fabric, as it is intended and understood that anyfabric which accomplishes the desired result shall be within the intentand scope of the invention and included in the term makingwire. as usedherein.

What we claim as our invention, sire to secure by Letters Patent, is-
